Background: This study evaluated the effects of resistance training (RT) and high-intensity interval training (HIIT) on systolic (SBP) and diastolic blood pressure (DBP) in hypertensive older adults undergoing pharmacological therapy over four and eight weeks. We compared the efficacy of RT and HIIT in reducing non-responders (NRs) between weeks 4 and 8 and analyzed time-course adaptations in NRs and responders (Rs).
Methods: Thirty-nine participants were randomized into RT-G ( = 13), HIIT-G ( = 13), or control (CG, = 13) groups.
Article Synopsis
- The study addresses the challenge of obtaining pure individual betalains in sufficient quantities by investigating a high-yield semisynthesis of betaxanthins using betalamic acid and amino acids.
- The color stability of the synthesized betaxanthins (ʟ-ProBX, ʟ-AlaBX, ʟ-LeuBX, and ʟ-PheBX) was tested across different pH levels, revealing that ʟ-ProBX showed the highest resistance to color change.
- Notably, ʟ-AlaBX and ʟ-LeuBX exhibited significantly higher antioxidant activity, indicating potential for their application as natural food colorants in food technology.
Background And Objective: Thyroid nodules are among the most frequent conditions, with a 10% risk of malignancy. The objective is to describe the frequency of demographic, clinical, and ultrasonographic characteristics of thyroid nodule pathology in adults and to explore the relationship with tumor malignancy.
Methods: An analytical, retrospective cross-sectional study in adults with thyroid nodules and nodular fine-needle aspiration performed in adult patients from a Colombian reference center between 2009-2019.
Colombian purple corn Zea mays L. by-products have been chemically characterized. To achieve this, after Amberlite XAD-7 purification and Sephadex LH-20 fractionation, the accurate anthocyanin and flavonol profile using UHPL-DAD-ESI-MS, total monomeric anthocyanin (TMA), polyphenols using Folin-Ciocalteau reduction capacity (FCRC), and antioxidant activity (DPPH and TEAC) of each fraction were performed.
